Exit Standby-Mode with RTC-Alarm after using BLE

Hello people,

I am working on a Project with the stm32wb55 which includes Low Power Modes (Standby) and Bluetooth (BLE).

When i turn off the Bluetooth part the controller can simply enter and exit Standbymode by my choice.

However if i activate BLE on a Button, work with it and want to enter Standbymode again the controller wont wake up anymore.

As i have heard the problem could be something with the cpu2 for example the RF.

Is there a way to shut down the cpu2 completely so i can enter the Standbymode like in the first example ?

Hello,

Standby mode is not supported when BLE is running. You shall turn off BLE to enter in Standby mode.

Best Regards
